IMPROVEMENT IN COTTON GIN AND PIQKIER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ENOCH OSGOOD, of the city of Boston, county ofSuffolk, in the State of Massachusetts, have invented a new and usefulImprovement in a Machine for Picking Cotton, or picking and ginningcotton at the same time, or for ginning cotton after. it has beenpicked, as the case may require; and that the following is a full andclear description of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, like partsbeing indicated by like letters in the several figures.

The nature of my invention consists in a peculiar construction andarrangement of parts, as hereinset forth. In the drawings Figure 1 is asectional view through my machine, showing its different parts.

Figure 2 is an end view of my machine.

Figure 3 is a sectional yiew through the picking apparatus, showing itsseveral parts,- and which is attachable or detachable at pleasure.

Figure 4 is a longitudinal elevation of my elastic roller.

Figure 5 is a longitudinal elevation of the revolving clearer.

Figure 6 is a side or longitudinal view of a pair of elastic rollerswith racks, double-concave or angular bar, and stripper or clearer. v

Figure 7 is an end view of the same, showinga double-concave or angularbar and a revolving clear r.

Figure 8 is a side view' of my pitman with key and strap.

In the drawings, A represents the frame or end pieces of my machine,held together by cross-bars, a. O is a driving-wheeh'motion-being givenit by a handle, b. On the shaft of this wheel is built or constructed myelastic roller, B, to be hereafter described. This wheel, 0, gears intotwo. othersfirst, G, which is secured to a crank, g, and towhich crankis attached apitma m c; secondly, it gears into another wheel, I,whichis secured to a\shaft, 17. On the opposite side a larger wheel, Q,is attached to this shaft, ,1), and it, in turn, gears with another,(not shown,) but which gears with a wheel on the end of revolvingclearer E when it is put on the machine, C represents a concave bar,under elastic roller B, which draws the ginned cotton between the two. DD-is a corrugated clearer, having suitable teeth at d 61. These clearingplates, D D, have their teeth turned inward towards the'roller B, asshown in section in Figure 9, by which means they act upon the cottonmore efl'ectually, and are completely protected from injury from stonesor gravel, either accidentally or intentionally introduced with thecotton. The pitman c is secured to this clearer and to oscillating bars,H, at I, and the crank 9 thus gives the clearer a vertical, nearlyvertical, up-and-down motion. t has slots, efwhich have pins,f, passingthrough them to limit the movement of the clearer. J is a trough, uponor through which to feed the cotton to the roll and clearer. gis itsbottom, made close most of the way, but where it inclines downward, at11., it is open, or as a rack. Oscillating bars, H, are pivoted in anysuitable way at 7e. Secured to the arms of O is a smooth ring or wheel,2', which has a friction-bearing upbn a pulley, j, attached to a shaft,70. On this shaft are several arms, Z, and to these are secured plates,m, serrated at their outer edges. This I call a doifer, Z, which isenclosed by a casing, 12, audits function will be described hereafter.

The operation of the machine as shown on figs. 1 and 2 is as followsFirst, after putting the machine in notion by means of arm I) and wheel0, the clearer D Dgets "its up-and-down motion through cranky and pitmanc, and the elastic roller revolves in the direction of red arrow q. Theunginned cotton is fed in through trough J. Itgoes down the inclined bedIt, and, in passing between the teeth of clearer D D, the seed arestopped or knocked backward, and, accumulating, they fall down, as shownby arrow 7'. The elastic roller B takes hold of the cotton, draws itdown and under it, and it passes. out, as shown at arrow s, between theroller and the concave 0. Whilst this is proceeding, the dofi'er Z isrevolving, and its serrated arms, m, playing closely againstroller B,brush or clean off any cotton which may stick to it, and brush or knockit down with the rest in the direction of arrow 3. i

The elastic roller]? is constructed as follows, (there are several waysFirst, I take sheets of India rubber and cloth, (linen being preferred;alternating them, forming thicknesses or layers, as desired, vulcanizcand cut them into hollow rings the size desired, as also to fit theshaft o-f-driving-wheel O, which is made with grooves in it, as shown byred lines at fig. 4, and I secure these rings tothe shaft byplacingbetween each, or

each pair, as necessary, a flanged ring, as shown in red lines, fig. 4;that is, having one or more internal pro- 'ectionsvto fit the co'rresondin r roove or "moves in shaft. These rin s have ins driven tin-ou hthem which J a a o u h a take into the elastic rings on each side, andthus prevent their turning. The cloth used in building up these rings Iprefershould run cdgwise from the shaft to or towards the'outer surfaceof 'the roller. If desired, I can coat the entire surface of the rollerwith rubber. I can build up my elastic roller by cutting the sheets,before described, (compound 0110s,) into strips of desirable width, andwrapping these edgwisc, spirally, and closely around theshaft, coatingthem with rubber if desired, but pressing the same spiral rings tightlytogether, and in any way prevent the coil from turning on its shaft,which may be done by ronghening the shaft and covering it by tenaciousrubber After the coil is put on and secured, Ivulcanize the roller.

Figure 3 shows my attachment for picking cotton, and, if attached to themachine before described, (after removing trough J, b ars H, and clearerD D,) will conduct the cotton to the roller B, as shown in beforenamedfigure; but in connection with which I use a revolving clearer, E, figs.3 and 5. Thisattachment is secured to the machine by means of the screw25, fig. 2. The toothed roller. Pfand the one above it, u, are placedoutward or furthest from the machine. There is still another roller, 1:,over B, and a smaller one, 20, over rack K. Belts L and L' passover-these rollers, and suitable connections are madeby machinery togive motion.

to these pulleys, cylinders, or rollers,".and belts. The teeth oncylinder I pick the, cotton, (seeds and 511, carrying it between P" andu, and between belts L and L over w and under 1), over rack K down upon.roller B,-nnd it is carr ied under it and between'it and concave 0.Whilst "this is going on the revolving clearer E, striking the cotton,knocks out the seeds, discharging or dropping them in an oppositedirection from the ginned cotton. The clearer E has/two curved arms, e,flanges, or lips, and their outward edges have a slight twist, so as togive the clearer a shearso that they will not strike it at their entirelength. The teeth of cylinder P are made adjustable by meahs of a rubberspring between the cylinder proper (or shaft) and'the outer metalliccasing. My machine can be used. with one roller or with two, as shown atfigs. 6 and 7, and as shown in my patents dated October 18, 1849, andMay 11, 18 58. This device I have tested in connection with my presentmachine. '13 B represent the two elastic rollers, the unginned cottonbeing fed in between racks N N, In connection with one of these rollersis a revolving clearer, E, to perform the function before described. Inthis attachment, L represents the double-concave or angular bar, totake'the place of concave C, as in the single machine, and M is anoscillating clearer over it, having teeth, 23:13, to scrape or doif theseed as soon as the cotton is drawn from it by the action of the elasticrollers. This clearer pushes the seed olf at each end, and over therollers. My pitman, c, as shown at fig. 8, is constructed so as to makeit light and strong. On its lower end are formedthe ears or straps,.z,between which is the lower half of the box, 3 the upper partof the earsor straps z, the other or upper half of the box forming a round hole forthe crank to pass through. Z is a tapering key under lower half box' andpassing through the two cars or sides of strapz 2, having a screw on itssmall end, to be drawnup by a nut to tighten up the box. My'machino canbe put in motion by any device or power that will produce the sameresult. This gin will gin all kinds of cotton, wet or dry, or indamp'weather, from the shortest Surat to the longest Sea Island, withoutinjuring the staple.

Having thus described my invention, what I claim as new, and desireto-secure by Letters Patent of the United States, isv 1. The elasticroller 13, made of rubber and cloth, the latter running edgewise fromthe centre or core to or towards the outer circumference, with theflanged metallic rings between the several compound rings, as described.the same constructed and operating inthe' manner as showir anddescribed, and for the purpose setforth.

2. The elastic roller B, made of rubber and cloth, wound around itsshaft or core spirally with strips, in the manner described, and for thepurpose set forth.

3'. I claim the combination of elastic roller 13 with concave bar G.

4. The combination of elastic rollersBB with the double-concaveorangular-bar L and clearer M, as described.

'5. The combination of elastic roller B, eorrugatedclearers D D, andconcave bar C, as described.

6. The combination of elastic roller B, revolving clearer E, and concaveG, as described.

7. The combination of picking cylinder, P", cylinders u, v,'and w,beltsL L, rack K, elastic roller 13, and revolving clearer E,constructed, arranged, and operating in the manner substantially asdescribed and for the purpose set forth.

8. In combination with the clearers D D, I claim the pitman c,constructed and operating in the manner shown and described andfor thepurpose set forth.
